Selection and characterization of the inheritance of resistance of <i>Spodoptera frugiperda</i> (Lepidoptera: Noctuidae) to chlorantraniliprole and cross‐resistance to other diamide insecticides

Abstract

The frequency of chlorantraniliprole resistance allele was moderately high in a field-collected population of S. frugiperda. The inheritance of chlorantraniliprole resistance was characterized as autosomal, incompletely recessive and monogenic. S. frugiperda showed cross-resistance to other diamide insecticides. These results provide essential information for the implementation of IRM programs to preserve the useful life of diamide insecticides for controlling S. frugiperda in Brazil. © 2019 Society of Chemical Industry.
